Application July 27, 1935, Serial No. 33,423 6 Claims. (01. 101163) This invention relates particularly to intaglio presses for engraving letterheadsor the like and has for its objects: I p

First, to provide a new and improved apparatus for engraving letterheads or the like from a web of paper which is fed continuously to the press and severed in sheet lengths after engraving or printing. 7

Second, to produce such an apparatus particularly adapted for use on intaglio presses made in the United States in which presses thecounters practically all face downwardly and thedies upwardly.

Third, to provide such an apparatus in which 0 the web may be fed and engraved and then fed to a cutting apparatus and the driers without smearing the engraved matter on the finished printed article.

Fourth, to provide such an apparatus that will transfer the engraved matter to a' drier automatically depositing the engraving upwardly to avoid smearing.

' Fifth, to provide such a device that may be conveniently made as an attachment, for use in 25 connection with presses already in operation with hand feeds'or the like.

Further objects and advantages pertaining to details and economies of construction and operation will appear from the description to follow.

30 A preferred embodiment of my invention is illustrated in the accompanying drawings, in which:

Fig. 1 isa perspective view with some portions broken away to. show operating mechanisms of an intaglio press with my improved feeding appara- 35, tus thereon.

Fig. 2 is a view semi-diagrammatic and in section on line 2-2 of Fig. 4.

Fig. 3 is a side view of the feeding and turning mechanism of amachine embodying my inven- 40 tion. 3

' Fig. 4 is a plan view of the feeding and turning mechanism.

Fig. 5 is a detail sectional view on line 5--5 of Fig. 4 showing means for reciprocating the 45 turner.

Referring to Fig. 1 of the drawings, I have shown the mechanismof the press and drier in dotted lines since they form no part of my invention.

50 I is the counter of an intaglio printing press and 2 is the die.

web 4 which is fed to friction feed rolls 5 and thence into a loop 6 before passing over the bed 7 of the press and between the counter and .die

55 thereof. The web 4 of the paper is fed by feed 3 is a supply roll for the paper jaws 8 and 9, 8 being a lower stationary feed jaw and 9 being a movable upper jaw, both provided'with disks H] for grasping the paper web and advancing the same. A spring I! is disposed to hold the jaws normally pressed together and they are mounted on a reciprocating slide l2 which is connected by a link It to a reciprocating arm it which is connected to a pitman l5 which is in turn connected to a cam follower l6 having a roller l1 engaging a cam [8. The throw 10 of the feeding jaws can be regulated by adjustment of the pitman l 5 through the bolt H1 in the slots 20 and by an adjustment of the point of attachment of the pitman E5 to the lever' M through the threaded block 2! and screw 22. The jaws 8 and 9 are actuated by means of a cam slide which is not shown in detail here, it being substantially identical with the cam slide arrangement for operating the jaws of the feeding means shown in myco-pending application Serial No. 612,678, filed May 21, 1932, for means for feeding webs of paper to printing presses.

The feeding jaws 8 and 9 are timed to grasp the web of paper and advance it a predetermined length between operations of the press to make an impression on the web. The jaws move the web a predetermined distance and then release the web and move back to initial position where they again grasp the web for the next feeding operation. A spring member 23 tends to hold the web in position and since it is not under tension, but hangs in the loop 6, the web remains in position for printing without being under tension.

The cut-01f means are similar to those shown in the above mentioned co-pending application and comprise the bracket 24 and plate 25 forming guide ways for the cutting member 26, which carries at its lower edge a blade 21 which cooperates with a stationary blade 28 for severing sheets from the end of the web. The cutting member 26 is provided with toggle members 29, 30, 3 I, and 32. The members 29 and 3! are pivoted to the member 26 and the toggle members 30 and 32 are pivoted to the bracket 24. The toggle members 29 and 3B are pivoted together and the members 3! and 32 are pivoted together and all are pivoted to the bar 33 which is normally urged to the right, as shown in Fig. 1, by the spring 34 which causes the blade to cut. A bell crank lever 35 pivoted at 36 and having a slotted end 31 engaging the bolt 38 on the bar 33 and provided at its other end with a cam follower 39 is provided to raise the cutting blade between feeding operations and the 'cam 46 engaging the cam follower 39 is so shaped that the blade is quickly actuated.-

at the end of a feeding operation. A handle 4| is provided for operating the cutting mechanism if the machine is not in operation and for controlling movement of the same.

A turner 42 is provided which comprises a rack 43 pivoted on the shaft 44. The rack has a plurality of spaced apart arms or fingers 45 extending toward the cutting means. Stops 45 are provided for engaging a severed sheet of paper which rests on the arms or fingers 45. The rack 53 is arranged to reciprocate from the position shown in Fig. 1 which will be referred to as the sheet receiving position, which corresponds to the dotted line position of Fig. 3 to the full line position of Fig. 3. A sheet of paper carried thereon is deposited on the continuous belt conveyor of the drier shown here in dotted lines at 41. A pinion 48 is provided for reciprocating the turner 42 and a rack 49 engages the pinion. The reciprocation of the rack causes the turner 42 to reciprocate. The rack is connectedby a pitman or arm 50 with a slotted member 5| passing around the drive shaft 52 of the cams 53 and 54. These cams are arranged to be rotated in clockwise direction as seen in Fig. 3, the cam 53 engaging a cam follower 55 for moving the rack to the right, as viewed in Fig. 3, and the cam 54 engaging a cam follower 55 for movement of the rack to the left, as viewed in Fig. 3. The movement of the rack back and forth causes the turner 42 to reciprocate from sheet receiving to sheet discharging positions and the cams are so timed that this operation takes place between cutting and feeding operations so that the sheet received from the press is deposited on the conveying belt 41 and in a turned over position.

A bed 51 is provided extending from die 2 to the cutting mechanism. The bed is formed of a portion of the bed I of the printing press and by the plates 58, 59 and 50 forming part of the feeding mechanism. The bed is provided with a slot or groove GI extending from the die to the cutting mechanism in the direction of movement of the web. The groove BI is of a width to receive the engraving on the web without smearing it and is. of a width also to be spanned by the sheet of paper passing through the feeding mechanism. The fingers 45 of the turner 42 are spaced similarly to receive the sheet of paper without touching the downwardly facing engraving thereon so that as the web of paper passes through the printing press it is fed face down with the engraving over this groove until the paper is turned with the engraving face up on the drier.
